Application filed September 2'7. 1906. Serial No. 336.512.

Paris, in the county of Lamar and State of Texas, have invented certain new and useful Improvements 111 Auxiliary l/Vaterlleaters and Smoke-Oonsumers; and I do declare the following to be a full, clear, and exact de scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in smoke consumers and water heaters for radiators. i

The object of the invention is to provide a water heater of this character adapted to be applied to or connected to the stack of a furnace to receive the smoke and gases passing therethrough, whereby said smoke and gasesare utilized for heating the, return or feed water for the heating system.

With the above and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings :-Figure 1 is a vertical sectional view through my improved snioke consumer and auxiliary water heater, showing the same applied to the smoke stackv of a furnace; Fig. 2 is a horizontal sectional view through the same taken on the line 22 of Fig. 1; and Fig. 3 is a side elevation partly iii-section of a modified form and arrangement of the device.

Referring more particularly to Figs. 1 and 2 of the drawings, 1 denotes the furnace, which may be of any character and is here shownas a steam boiler furnace; and 2 denotes the boiler, which may also be of any construction. The furnace 1 is here shown as provided with a smoke box 3 arranged at one end of the boiler and having connected thereto a short stack 4. On the upper end of the stack 4 is arranged the improved smoke consumer and auxiliary water heater 5, said heater being here shown in the form of an upright cylinder closed at its lower end and provided with a removable cover 6 at its upper end In the cover 6 is formed a centrallydisposed discharge pipe 7, through which the smoke and gases are discharged after passing through the cylinder.

Arranged in the cylinderof the heater 5 is a series of inverted cone-shaped or concave partitions 8 that constitute combined smoke deflectors and water distributors, the outer edges of which engage the inner walls of the cylinder and are secured thereto in'any suitable inanner, said cylinder being preferably provided with annularribs or cleats 9, upon which the outer edges of the partitions S are adapted to rest. In the center of each of the partitions 8 is formed an aperture 10. Between each of the partitions 8 is arranged a seriesof c0ne-shaped or convex disks 12, that constitute water -distributers and which are of somewhat less diameter than the cylinder of the heater and are supported upon and slightly above each of the partitions 8 by means of short lugs 13. The disks 12 are arranged concentrically in the cylinder oi the heater with the points of the SMDWPIOjGCting slightly in the apertures of the partition 8.

On the top or upper disk 12 is secured centrally-disposed cup 14, into 'whlch is adapted to be discharged the return. water from a heating system, said water being conducted to the heater 5 by a return pipe 15. The end of the pipe 15 is adapted to be in sorted through the top of the heater in position to'dischargc the water into the cup 14 as hereinbefore described. The upper edge of the cup is preferably provided. with a se ries of notches 16 by means of which the water overflowing from the cup will be evenly distributed onto the upper disk 12, from which it will run down onto the partition 8 immediately below said disk. The water upon discharging or running onto the partition 8 will pass between the same and the lower edge of the disk 12 and will then rundown said partition and through the aperture in the bottom oi the same onto the next disk, and so on until the bottom of the heater is reached. The water upon reaching the bottom. of the heater is discharged therefrom through. a valved discharge pipe 17, by-

Which it conducted to a suitable strainer 18 arranged in a receiving tank 19, from which it is forced to the radiators or heating pipes by a suitable pump 20.

The water in passing over the disks and partitions in the heater will be acted upon by the smoke and gases passing through the same from the stack of the furnace and will be heated thereby. The cinders or other foreign matter entering the water from the smoke as the same passes through theheater ,Wlll be removed irom the water in passing through the strainer 18, so that the water ontering the tank 19 will be pure and free from Q create all matter which would interfere with the operation of the pump or tend to clog the pipes of the radiators or heating system,

If desired the discharge end of the steam exhaust pipe may be connected with the stack, as shown at 21, thereby utilizing the heat from. the steam to assist in heating the water. The end of the stack, 4. which enters the lower end of the heater is adapted to projec't a suitable distance above the bottom of the cylinder to prevent the Water from running into the stack and in said projecting end of the stackjs preferably arranged a fan 22, I

which may be operated in any suitable manner and will aid in forcing the smoke and gases through the heater and maintain a draft for the furnace. I

In Fig 3 of the drawings is shown a modilied arrangement of the heater, the latter be fan 24-, as shown end of the same may be readily opened and ing here shown as applied to the side of a" stack and connected thereto at its lower end by an inlet pipe 23, in which is arranged a The upper end of the heater is connected to the stack by a suitable discharge pipe 25, preferably arranged at an angle to facilitate the passage of the smoke from the heater, as will be understood; In.

the latter form of the device, the stack is preferably provided immediately above the pipe 23 with a damper 26, whereby the smoke and gases from the furnace may be permitted to pass directly througl'i the stack or directed through the pipe 23 to the heater.

The heater shown in Fig. 3 is similar in construction and arrangement to that shown in connection with the first figures of the drawings, except that the fan 24 is arranged below andoutside of the heater, as shown.

By providing the heater with a removable cover as hereinbefore described, the upper the partitions8 and disk 12 'remoyed'there from for cleaning or other purposes,

At thelower end of the heater is arranged a discharge. valve 27 by means of which the same may be drained and cleaned out.

. From the foregoing description, taken in connection with the accompanying draw ings, the'construction and operation of the invention will be readily understood Without redpiring a' more extended explanation.

arious changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention, as defined by the appendedclaims.

Having-thus described my invention, what I claim as new-and desire to secure by Let,-

ters-Patent, is :5

An auxiliary water heater and smoke consumercomprising a receptacle adapted to be arranged on the upper end of the smoke stack of a furnace, a series of apertured partitions arranged one above the other in said receptacle, a series of disks arranged to altertherefrom. I In testimony whereof I have hereunto set my hand in presence of two subscribing witmesses.
